Just want to give everyone a heads up that we have some server maintenance scheduled to start tomorrow at around 8:30am Pacific time - it will likely take the site offline for between 1-4 hours. One of our hard drives is acting up and we may need to replace/upgrade it.

Apologies for any inconvenience. If you are competing for solving percentages you may want to play only as a guest until this is resolved sometime tomorrow afternoon/evening, as some data loss may occur.
